The hiding place

A man is ready is check out from his Hotel and while he waits for the Taxi he feels a strong urge down south and instantly knows, he will not make it. So, he lifts one of the plants out of its pot and releases himself. Afterwards, he leaves the Hotel in great haste. One week later he receives a letter from the Hotel he stayed in: Dear Sir, All is forgiven,but please, for the love of God: just tell us where!! Best Regards Hotel
